What does KNX cost?
KNX cost depends on how many functions you want, not on a flat rate. venfree calculates the device cost for your house room by room, with real prices, free and without ETS.
Calculate cost for my houseWhat drives KNX cost
Each switched light, dimmed light, blind and heating circuit needs channels. More functions means more devices, this is the main cost driver.
Large multi-channel actuators are cheaper per channel than many small ones. The manufacturer matters too, and venfree compares them.
KNX has no monthly costs. After material, cabling and programming the system runs without subscriptions.
Example: single-family house
A typical single-family house with light, blinds and heating across its rooms needs several switching, dimming, blind and heating actuators plus sensors and a power supply. The device cost for these bus components usually lands in the low to mid four-figure range, depending on how richly you equip it.
The exact figure depends on your rooms and functions. Cabling and programming come on top and depend on your electrician. venfree gives you the device cost precisely, in minutes.

Frequently Asked Questions
What does KNX cost for a single-family house?
The device cost for the bus components of a typical single-family house (switching, dimming, blinds, heating, plus sensors and a power supply) usually lands in the low to mid four-figure range, depending on how many functions you want per room. venfree shows you the exact figure for your rooms in minutes. Cabling and programming come on top and depend on the electrician and the project.
What does KNX cost per square meter?
A flat rate per square meter is misleading, because the cost follows the number of functions per room, not the floor area. A small, densely automated apartment can cost more than a large, simply equipped house. Plan your actual rooms in venfree to get a real figure instead of a rule of thumb.
Is KNX worth it in a new build?
In a new build the cabling is being done anyway, so KNX is at its most economical there. Whether it is worth it depends on your expectations and budget. venfree lets you price your concrete plan for free before you decide.

Yes. With venfree you plan your KNX system for free in the browser, without an ETS license and without an account. You enter rooms and functions, and I build the full device list with prices.
